The Dow Jones Industrial Average saw a huge decline Monday. At its lowest, it fell over 1,500 points — the index's largest point-drop ever.
That was an over 6 percent loss, which eventually settled at under 5 percent at the bell. The drop effectively erased all the gains it made so far this year.
The decline is the largest since August 2015. But this might just be a normal stock market correction after a booming start to the year.
The Dow isn't necessarily a great indicator of market health. It's based on the average stock price of 30 huge companies, which might not be a good sample for today's diversified market.
